Parker S71-3N6-6F Hydraulic Hose Valve Fitting 3/8 in 5000 Psi

Product Description

The PARKER S71-3N6-6F is a stainless steel hydraulic hose valve fitting designed for use in high-pressure hydraulic fluid lines. Rated to 5,000 psi, it provides a reliable connection point between hydraulic hose assemblies and valve ports where leak-free performance is critical. The 3/8 inch thread size makes it a common choice in mid-size hydraulic circuits found across industrial, mobile, and fluid-power applications. The stainless steel construction resists corrosion in demanding environments. This fitting is installed by hydraulic system technicians, pipefitters, and fluid-power specialists working on both new assemblies and field repairs.

This valve fitting is suited for hydraulic systems operating within a temperature range of -35 degrees F to 250 degrees F. It is appropriate for use in industrial machinery, mobile equipment, and fluid-power circuits where a 3/8 inch valve-port connection is required. The 5,000 psi pressure rating covers a wide range of standard and medium-high-pressure hydraulic circuits. It is packaged individually and sold in single-unit quantities, making it practical for both maintenance stock and one-off repair jobs.

Key Features

• 5,000 psi maximum pressure rating for high-pressure hydraulic service
• Stainless steel construction for corrosion resistance in harsh environments
• 3/8 inch thread size for compatibility with standard valve-port connections
• Operating temperature range of -35 degrees F to 250 degrees F
• Single-unit packaging for easy stock replenishment or field repair

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose and valve assemblies requiring a 3/8 inch valve fitting rated to 5,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic system technician or pipefitter. Always depressurize and bleed down the hydraulic system fully before removing or installing any fitting. Inspect threads and sealing surfaces for damage before assembly, and use the appropriate thread sealant or O-ring compatible with the system fluid. Torque to the fitting manufacturer's specification using a calibrated torque wrench; do not over-tighten stainless steel fittings, as galling can occur.
